To all wtoyat it may concern:

Be itA known that we, ROBERT H. PETERS, residing at Batavia, in the county of Genesee, and LEONARD A. MASON, residing at Buffalo, in the countyof Erie, State of New York, vCitizens ofthe United States, have inf vented new and useful Improvements in Dia- 4Heretofore it hasl been the-custom to corrstruct av'diap'er'from a` large rectangular-sheet of woven fabric which was folded diagonally several times until a triangular diaper was ,Obtained of a size suitable infant. A dia er when thus folded contains are spread abnormally inplacing the breechliap between its'legs and an abnormally large lump is formed on the abdomen', which domen o l Iso presses the same on account of 'fastening to,- gether the breech and Waist iiaps one above the other over'the abdomen. An excessively thick dia erb'etu'feen. the leg's and on the abip'an infant is the principal cause of bow-legsand bowel disorders and also the cause ofmuch discomfort on account of the excessivewarmth roduced by the same As v.is well known, this ind :'of'diaper is folded the -greatest number of tinies when the infant is v smallest, andthe number of folds is gradudue to the factt ally reduced to increase the size of the da er as the child grows. It will thus be seen't at the diaper is of the greatest thickness and op? erates most injuriously in spreading 'the legs and pressingthe abdomenof the infant yat a time'when it is smallestand has less need for 'a thckdiaper, Whereas the dia erbecomes thinner at' af'timewhen the anthas' be-v4 come largery and could not only wear a'thick diaper with more comfort and less injury, but actually requires a thicker diaper on account of th`e".`increasing` moisture which hasta be absorbed.v Afurther 4objection to thediagonallyffolded ydi-a ers \I1 OW commonlyA used is liata diaper thus folded and applied to ank infant usuallv brings. around its waist thefstret'chable which is arranged diagon loose to or the particular ing yt same.

The body of this diaper consists of a.sub"

stantially triangular sheet of Woven fabric the longitudinal and transverse edges and a; breech-flap` b at the junction of the trans- 'v'erse edges. This-bodyis so constructed vhaving a main or long'longitudinal edge a@ and two main or long transverse edges a a', formingv waist-flaps' b b at the junction of' edge is rendered practical y non-stretc able',

whilepthe other main transverse edges a a are arranged obliquely to the warp; and weft of the fabric,y whereb these edgesyar'e rendered stretchable.y n practice the non# lstretchable edge portion 'forms the waistband of the diaper, whilel the stretchable edges al v a form the leg-bands thereof.-

VIn applying the diaper the waist-naps are passed crosswise around the Waist, and the reech-'lap is. passedupwardly between the` legs, the several flaps being then secured toether in a well-known manner over the ab.-` omen.'-4v `When the diaperlifs thus ap lied, the unstretchable waistband bears mly roo against'thel waistandprey'ents the, diaper from becomingA displaced, while the stretchtogether ata distance from'their'ends in or der to obtain a lirm hold on the same, the extreme outer ends or tips of the fla s are unnecessary. These ends are therefore truncated, forming a short longitudinal edge c onthe tip of the breech-Hap, which is parallel with the warp and joins the converging ends of the oblique edges, and two short trans# verse'edges c c at the tips of the waist-flaps, which are arran ed at lright angles to the warp and each o which joins one end of the long lon 'tudinal edge and the adjacent end of one 'o the oblique ed es. @wing to the short edge c being .paralle with the warp,this edge is incapable of stretching lengthwise in the same manner as the long or main longitudinal edge on the o posite part of the diaper, while in use the s ort transverse edges c c of the diaper are subject te dia onal strains the same as the oblique edges o the diaper, whereby the edges c are caused to stretch in the same manner as the oblique edges. ln practice the long and short longitudnal'edges of the diaper are preferably selva ed, seamed, or hemmed to prevent raveling, iut the long oblique and short transverse edges are left in a cut or unhemmed condition to permit the same to stretch freely in a diagonal direction.

F or the purpose of providing the diaperwith the required capacity of absorbin moisture that side of the dia er' which is p aced next tothe body is provi ed with a pile surface D, while its opposite side is wholly pileless. This pile surface preferably does not extend over the entire body of the diaper, but` stops short all around the ed es thereof, forming a pileless mar n e on t e body at its edges and a mat or p' e surface of substantially triangular form within the pileless margin. The pile surface bears loosely against the bod and enters the wrinkles, thereby edectual y absorbing all Vmoisture which is present, whereby soreness and irritation is avoided. It is preferable to shear or cut theloop formin cap' Iaryaction of the same; but, if desired, these loops ma be left uncut if the character of the materia is sufhciently absorbent.

' In order to bring as much pile surface as possible in contact with the body and render the same most efficient without, however, producing an undesirable thickness of the diaper between the legs of the child: the longitudinal edge f of the pile surface is made parallel with the adjacent main longitudinal edge of the body, while the oblique trans verse edges g g4 of the pile surface are curved concavou'sly or recede from the oblique edges of the body near the end of the breech-flap, forming a narrow lobe T1, of ile surface on the breech-flap which can be placed between the legs for absorbin the moisture without inconvenience. A iaper is .thus formed which has a comparatively wide pilevsurface on the waist-flaps for producing a large absorbing surface in the seat of the diaper and a narrow pile surface on the breech-flap which passes between the legs of the infant, thereby obtainin the maximum absorbing capacity with t e least tendency of spreading the legs unnecessarily. By forming the bodyof the diaper with a pileless margin the same can be fitted closely to the body, while the mat or pile surface within the margin furnishes the necessary thickness to eiiectually absorb the moisture. j

` Although our improved diaper can be produced in various ways, we prefer to weave them successively in the form of a strip which issubsequentl cut at predetermined places into individua diapers. As shown in Fie. l., the diapers are woven in a strip which is equal in width to the distance between the main and short longitudinal edges of the diaper-body, .triangular pile surfaces being produced thereon at intervals and in alternately surfaces being formed between adjacent pile surfaces. The diapers are successively severed from the strip by oblique cutsi, extending centrally through the oblique pileless surfaces between adjacent pile surfaces and trimmed by -transverse cuts y' for removing the ti s at the far ends of the oblique edges and t e longitudinal edges. The near ends of the oblique cuts in the strip are se arated so as to form the short longitudinal e ges 'c of the diapers. cut, a pllurality of diapers is formed, each of which as a long longitudinal selvaged edge on one edge, a short longitudinal selvaged v, edge on the opposite edge, two oblique cut of the long longitudinal edge with the diverging ends of the oblique edges, a pileless mar- `n and a ytrian l'ar ile surface within the the. ile surface in order to obtain the fulles g1 gu p pileless margin.
